Automation is a key part to online success.
Are you going to hire a bunch of in house employees to do your SEO, link building, competitive research, keyword research, domain analysis etc?
It would cost you a lot of money, time and hassle to get something like that done. It can be done much more effective.
You need to use automation.
The right tools can make or break your success in the online world. In addition, they can also save you a lot of time. Here are some tools I have found and which is used for my online business are:
1) A Backlink service called LinkAloha. It automates all aspects of link building and gives you a nice and diverse backlink profile to boost your site to the top of the searchengines.
2) An aged domains finder tool. You can use it to find domains which are allready receiving traffic. Premium domains for low prices.
3) A serp tracker called SerpWiz. You need a tool like that to automatically track your efforts and rankings from google.
4) A keyword research tool called nicheshark. It will automate your entire keyword research, and will find new niche ideas for your business which you can expand and work on.
Those are tools you need to succeed with your business online these days if you want to stay ahead on the competition.
My advice, take a look and maybe you find them interesting

Good Find! I used Domainpeeker myself and was able to snag a bunch of high PR domains cheap – definitely a good tool. Price is alright too. Ben
What about Senuke? Do you recommend Senuke??
It really depends how you use it. Don’t use fresh web2.0 profiles, those won’t have any value. If you use such tools for automatic submission, use established, old accounts only. And keep in mind that (in my opinion) the strength of Senuke and similar tools is more in diluting an existing link profile, not so much in establishing a new one.
Quality over quantity, this is valid for backlinks as well, in particular after the Penguin Google update. Regards, G.
